Hi friends!

I need some help with OB files. I’m trying to import into the iPad app Procreate.

USDZ and OBJ are acceptable but they MUST have a UV map attached to it.

I’ve contacted Procreate and their response said “some elements do have UV maps, but not all of them”

Please help! Here's an example of a file that I'm using

Woah, I had no idea procreate had a 3D mode now! So the incompatibility is probably that the brushes use vertex colours instead of a UV. I believe if you're getting them from sketchfab they attempt to do some of the conversion process but it's only for some brushes. are you working with sketchfab models exclusively or could you try exporting manually from OB?

mikesky•1/14/22, 2:46 PM

Also, may want to give them a poke about supporting glTF models

OBJ is good and simple but not really strict on standards which glTF helps a lot with

mikesky•1/14/22, 2:47 PM

Pipeline is really important, so knowing use cases like this is good for informing future development

andyleoOP•1/14/22, 5:25 PM

Yeah the 3D painting features are really cool imo. I’m only using sketchfab bc it’s so easy for students to upload. I’m using this in a HS Art class. I’ll look into exporting straight from OB but I’m thinking it’ll make a lot more work for me.

mikesky•1/14/22, 5:28 PM

Another poke for me to get to Icosa integration sooner rather than later

That totally makes sense, I'll see what I can do. What ingest format are you using out of the two?

andyleoOP•1/14/22, 7:12 PM

“Ingest format”? Sorry I’m new at this

Zandy•1/14/22, 8:52 PM

Just a heads up that the hulls do not have UVs thats why they do not bake properly in unity. You have to bring them into Blender or substance painter to create new ones for them to work.

Aandyleo “Ingest format”? Sorry I’m new at this

mikesky•1/14/22, 10:00 PM

Ah sorry, i mean when it comes into procreate do you use usdz or obj?

mikesky•1/14/22, 10:01 PM

Good to know

Perhaps you might need another step in your pipeline for now, asset prep can be half the work sometimes

Mmikesky Ah sorry, i mean when it comes into procreate do you use usdz or obj?

andyleoOP•1/14/22, 10:02 PM

I have never done this so I’ll do whichever works. We’ve primarily used the hull brushes so that’s probably bad news

andyleoOP•1/14/22, 10:04 PM

And I would say that the hulls lend themselves to procreate the best sooo….

mikesky•1/15/22, 3:34 PM

So does it just fail to import if there's no UVs, even if they're blank? I'm surprised because procreate is kinda making it's own UV maps when you paint on the objects

mikesky•1/15/22, 3:36 PM

Zandy's probably right, you may just need to do a bit of pre-processing first just to set them up. Will note this for pipeline improvements though, if that's something we can support our end!

andybak•1/15/22, 6:50 PM

Would be fairly easy to add that to toolkit. I'm thinking of making that more like our general purpose "sketch post processing tool"

Good evening! Encountering bugs with snap to grid. It’s definitely off. It will snap only in one direction. If you look at the plane or object from a different viewpoint, it’s crooked. Had this issue even building and lining thing up manually. It’ll always be off. The only way to get it perfect is using two guides and snap to x and y, otherwise it’s like the leaning tower of Pisa in one direction.

Evl_Stache•1/18/22, 1:45 AM

@Zandy sounds like you are trying to do something that would be better done in conventional CAD.

Zandy•1/18/22, 1:59 AM

Thanks @Evl_Stache Not interested in CAD. Prefer the painted organic look and feel. Painting architecture in VR is extremely meditative. Like in these: https://youtu.be/wsCo-UmUprE

@Zandy fair call. could be good to have some base geometry to provide a base to paint over

Evl_Stache•1/18/22, 2:52 AM

Zandy•1/18/22, 2:59 AM

For me personally, it’s not the same….I see the advantages of cad programs and blender, etc for buildings but find it’s too clinical and loses the “emotion” that is put in a piece when you paint it organically. You miss the true texture and feel of a painted piece. It’s a completely different experience.

Evl_Stache•1/18/22, 3:07 AM

oh i get you i was more suggesting you could just have a reference cube you paint over that gives you height and square.

Zandy•1/18/22, 4:04 AM

Open Brush and TB have guides that you can use for that.

andybak•1/18/22, 9:21 AM

That's peculiar. I can't even imagine how that would be the case. Do you have any images that show the problem?

Zandy•1/18/22, 1:19 PM

@andybak just sent a DM

Zandy•1/18/22, 1:23 PM

It seems to happen more when you add additional strokes to the scene after the initial one. Maybe it’s similar to when you paint multiple strokes on a guide and it moves as you add more strokes?

andybak•1/18/22, 3:09 PM

I'm not exactly sure what you're doing - but you seem to be using angle snap with the straight edge tool? Angle snap is only really for duplicating selections. Grid Snap would be better for drawing exactly vertical or horizontal strokes.

Zandy•1/18/22, 5:19 PM

Used the angle tool to have a straight line to snap. It was used before the additions from OB. Thanks for the clarification on the new settings!

andybak•1/18/22, 8:07 PM

Ah. I've not actually investigated how the new angle snap works with the straight edge and the existing angle tool. (tbh I forgot the latter existed!)

Zandy•1/18/22, 8:11 PM

No worries! Will try again without the angle snap first and see if the issue persists with it.

Hello! Is there an FAQ for openbrush? I have some questions but don't want to spam with stuff that is already answered elsewhere. For example, does OpenBrush have LIV support?

Recent problem/bug exporting with experimentals. The newest steam version wont export fbx or glb, but if I open Andy's experimental build with the geo brushes V 1.0.86 it exports fine.

andybak•1/25/22, 11:24 PM

By "newest Steam version" - do you mean the beta or the main version?
What happens when you try and export a glb or fbx? Error? Or it's just a broken file?
Probably being a bit dim here but what is "experimental build with the geo brushes"? Can you post a link to the build you mean?

Zandy•1/25/22, 11:24 PM

Hey @andybak Steam Beta. It says failed to export FBX and GLB. Your personal experimental build with your geo brushes, that I think you put it together last spring.

Zandy•1/25/22, 11:28 PM

I was able to export from the recent version of steam beta a couple of weeks ago with no problems. This happens with pieces I could previously export.

Hello- I have some very noonish questions. Context. Im on a quest 2. Sidequest on a mac. I haven’t been on a PC since dial up modems. At the most basic level Im trying to export the highest quality and most color accurate stills of the works created within Open Brush. I tried using snapshot through the labs panel but it was glitching with screen tears in the preview and also shows up like that when I view on my mac. Making a gif does work without tearing but is super low resolution. I can cast to my PC and then screen record the cast but it does not look anywhere near as high res as it does in the VR headset. - the color also feels a bit dead/flat. I have a quality monitor-Oddly I use to manage a 2D/3D production studio for extremely high end global marketing images. But I had a great IT dept!

I may have done some damage by trying to side load as well as adjust setting in side quest but I think i returned all the settings to default and I don’t think my attempt to side load the SDK worked as I see no new brushes.

Im a bit of a disaster on this and ID be happy to support Open Brush with modest donations along the lines of any paid app. Many thanks in advance. I am extremely excited about using this software both in digital space and as a tool for my meat space art work.
